Stellar Sea Lion Bull on Haul Out

The Alaska Ecosystems Program conducts research on Steller sea lions and northern fur seals. Research projects are designed to assess the status of these species under the ESA and MMPA and to improve knowledge of their ecology and behavior.  In addition, research on these species is directed at gaining a better understanding of the role that these species play in the Bering Sea and Gulf of Alaska ecosystems in order to provide advice for management of human activites that may affect the conservation and recovery of these species.
